4.5 Glossary
Carrier-grade NAT Describes a method in which the internet provider assigns a private internet address to its customer,
which is only valid for the length of one internet dial-in. This method is often used in LTE routers.
Such routers cannot be provided with a permanent host name via DDNS. In this case, a VPN tunnel
is an option.
DDNS
Dynamic Domain Name Service. A DNS service, whose entries are short-lived and are updated
automatically. Often used for routers with a volatile, public IP address. By giving it a permanent host
name, the router can be accessible. Not suitable, if the internet service provider only assigns private
addresses (carrier-grade NAT). Known DDNS providers are DynDns and No-Ip.
DHCP Dynamic Host Configuration Protocol. Allows central administration of network parameters such
as IP address, subnet mask, name server etc. for all devices in a network. The gateway is a DHCP
client; a DHCP server has to be provided in the network environment.
DNS Domain Name Service. An internet service that is able to convert easy-to-remember names such as
www.google.com to IP addresses like 173.194.113.151 (IPv4) or 2a00:1450:4005:808::1018 (IPv6),
which are required for communication via the internet.
DNS-Server A server providing the DNS service. The IP address of one or more such servers is uniquely entered
during the network configuration of an internet-enabled device. From now on, it is possible to enter
easy-to-remember host names instead of hard-to-remember, and optionally frequently changing, IP
addresses on the device.
Ethernet See IEEE 802.3
Firmware Describes the permanently installed software on a device, e.g. the gateway or single components
of your ZigBee network. Although the software is installed permanently, it can be updated on ubisys
devices.
Host Name Name of a device (PC, server, gateway, NAS, printer etc.) in the internet or in the local network.
Examples: www.google.com or smarthome.dyndns.org, or
ubisys-g1-0815.home.local.
IEEE 802.3
Also known as Ethernet. A number of international standards for wired networks connecting PCs to
many other devices such as the gateway, NAS, printer etc. Basis for the IP based network.
IEEE 802.11 A number of international standards for wireless networks connecting several devices such as PCs,
tablets, smartphones etc. with each other. Foundation for the IP based network via Wi-Fi.
IEEE 802.15.4 An international standard for wireless networking of objects. Low power consumption, high reliability
and safety feature the standard. Amongst other things, it is the basis for ZigBee PRO and ZigBee IP.
IP, IPv4, IPv6 Internet Protocol. Basic protocol of networking for the internet. Currently, version 4 (“IPv4”) is the
most distributed; a gradual change to version 6 (“IPv6”) is underway.
IP Adresse Address of a web-enabled device. IPv4 addresses have the form 192.168.0.211, IPv6 addresses
the form fe80::4138:954a:d196:3c37. The IP address has a part that indicates the network and a
part, which identifies the device in the network. For this, the net mask needs to be specified in IPv4.
This will determine where the subnet address ends and where the device address begins. There are
public and private IP addresses. Private IP addresses can only be used within the local network;
they are not being routed by the internet router and can therefore be used as many times in different
networks.
Name Server See DNS-Server
NAS Network Attached Storage. A network-enabled storage device, usually one or several hard disk
drives, which is power-efficiently embedded into the network without the need of operating an entire
PC.
NAT
Network Address Translation. A method, where an internet router provides internet access to several
devices in the local network through a single public IP address. For this, every device is assigned
to a port. Through this port, the following data traffic can clearly be assigned to each target device.
Besides automatically assigning ports when establishing a connection from the private network side
to the public side, NAT routers are able to direct incoming data traffic to previously specified ports of
certain devices, e.g. your gateway, a webcam, a file server in your network etc.
Net Mask See Subnet Mask.
